linux下基于指定目录及子目录下所有文件中指定字符串进行替换

使用sed命令进行替换:

sed -i 's/old_string/new_string/g' /path/to/directory/*

使用find命令结合sed进行替换:

find /path/to/directory -type f -exec sed -i 's/old_string/new_string/g' {} +

使用grep命令找到包含指定字符串的文件，再使用sed进行替换:

grep -rl 'old_string' /path/to/directory | xargs sed -i 's/old_string/new_string/g'

使用awk命令进行替换:

awk '{gsub(/old_string/, "new_string"); print > FILENAME}' /path/to/directory/*

使用perl命令进行替换:

perl -pi -e 's/old_string/new_string/g' /path/to/directory/*

使用Python脚本进行替换:

import os

def replace_string(path, old_string, new_string):
    for root, dirs, files in os.walk(path):
        for file in files:
            file_path = os.path.join(root, file)
            with open(file_path, 'r') as f:
                content = f.read()
            content = content.replace(old_string, new_string)
            with open(file_path, 'w') as f:
                f.write(content)

replace_string('/path/to/directory', 'old_string', 'new_string')
